IivIPRQVEMElJT IN MECHANlCAL MOVEMENTS.

Specification forming part of Letters Patent No. 134,766, dated January14, 1873.

To all whom it may concern:

Be it known that I, WEBs'rEit PARK, of Norwich, in New London county,Connecticut, have invented certain Improvements in Mechanical Movements,of which the following is a specification:

My invention consists of a simple and novel mechanism, in a very compactform, tocommunicate a diminished motion or increased force between aseries of wheels, especially adapted for registers of meters or countersfor machinery of various kinds, but which may be used for raisingweights and many other similar purposes.

Figure l is a side view, full size, of a series of three cylindersembodying myinvention as arranged for a register or counter; Fig. 2 is aview of one end of the cylinders, showing the pins or teeth, and Fig. 3shows the eccentric upon the opposite end of the cylinders and thehollow between the eccentric and rim, like the ordinary machine-pulley.Fig. 4 shows the shaft on which the cylinders revolve, with a pin fixedin the shaft; Figs. 5 and 6 show two forms of the T-plate in which theeccentric turns, and Fig. 7 shows the top edge of the T-plate and theform in which its arms are bent forward so as to engage with the teethof the next cylinder.

A A are the wheels or cylinders turning loose upon the shaft B, which,when used for a counter, should be large enough to have the ten figuresequidistant upon their surface. 0 C are pins or teeth projecting fromone end of the cylinders, and D is the eccentric upon the opposite end.These cylinders are preferably cast of soft metal in one piece, with thepins, eccentrics, and figures upon them. E E are the T-plates havingholes S S through their centers, in which the eccentric freely turns,thereby swinging the plate; and I I are the arms of the T, which arebent forward, as shown in Fig. 7, so as to engage fully with the pins ofthe next cylinder. The plates are prevented from revolving instead of orwith the cylinders, either by forming a small slot, 0, in the bottom ofthe plate, as shown in Fig. 5, so as to slide freely up and down uponthe fixed pin N in the stationary shaft B, or by extending the bottom ofthe plate, as shown in Fig. 6, between and outside of the cylinders,where it may slide up and down through any stationary guide G; and thebottom'of the plate, where it passes the ends of the pins on thecylinder, should be made wider than the space between the pins, as shownin Fig. 6, to prevent its catching on the pins, the object of thismovement being to communicate motion from one cylinder by means of itseccentric operating through the non-revolving arms I I upon the pins ofthe next cylinder, so as to turn it one pin in the same direction withevery revolution of the first cylinder, and in the same manner throughany number of cylinders. This movement also forms a stop or check, sothat no cylinder can be turned except through the agency of the first,as either one or both of the arms I I are at all times engaged with thepins.

It is evident that this movement may be made of any desired size andstrength, and that there may be any desired number of pins or teeth, thethrow of the eccentric being about half the distance between the teeth.

When this movement is used in a register or counter the ten figuresshould be arranged conspicuously upon the outside of each of a series ofcylinders, all turning freely upon the same shaft, and each cylindershould have ten pins upon its right end, thus being a pin opposite eachfigure, the cylinder at the ex treme right being connected with themeter or the machine, whose motion is to be counted by any ordinarywheel-work, so as to move the first cylinder one figure with each motionof the meter or machine, thus showing the units. The second cylinder ismoved one figure by every revolution of the first by means of mymovement hereinbefore described, thus showing the tens. The third showsthe hundreds, the fourth the thousands, the fifth the ten thousands, andso on; the whole index being read from left to right as the figures turnopposite a given point.

If desired to increase force for raising weights or other like purposes,there need be no figures upon the cylinders, but the whole device shouldbe made much larger and stronger, when, by applying any force to turnthe first cylinder, the second is turned with a tenfold greater force,and so on, like an ordinary train of wheel-work; my movement beingprecisely the same, except in size, for these various uses.

I claim as my invention- 1. The combination of the eccentric D, arms II, and pins or teeth 0 C, substantially as described.

2. The cylinder A having the pins or teeth upon one end and theeccentric upon the other, all cast in one piece of metal, substantiallyas set forth. r

3. The combination and arrangement of a series of cylinders, A, eachhaving an eccentric, D, pins or teeth 0 G, and non-revolving arms I I,all arranged upon one shaft, B, and operating substantially as hereindescribed.
